Play will began promptly at 1:00 pm and conclude by 5:00pm. Lunch will began serving at 11:30am. Cold drinks will be available and we will have a keg for the COOLING DOWN TIME.
This will be a half day A and B Scramble Tournament. A player will play with all other players in his group. Ladies will be teamed with partners in the A or B groups as they choose. In addition to TROPHIES there will be a drawing for a generous group of DOOR PRIZES.
To ensure the proper amount of court space, food and drinks, complete and send in the entry form as soon as possible, but no later than September 24, 2003. We have more room for players and encourage you to contact your associates to participate in the tournament. We are again inviting players in the Geological Society to join us so as to have more players and more fun.

Wednesday, October 15, 2003: SMT and SIPES Foundation to Offer a Reprise of the Distinguished Instructor Short Course: 8:30 AM ­ 4:00 PM at The Petroleum Club, Houston, TX

Cost:

Early Registration (before September 15) $125 (SIPES members, $100)
Registration (After September 15) $150 (SIPES members, $150)
Cost includes: Course textbook (Seismic Amplitude Interpretation), breakfast snack and buffet lunch.
Contact: B. K. Starbuck, Secretary, Phone: 713/651-1639 E-mail: bkspee@aol.com
Instructor: Fred Hilterman
Course Description:
Two principle objectives of seismic interpretation are to recognize a hydrocarbon anomaly (the prospect) and then to validate its structure and
composition. With today's advances in 3-D workstation interpretation, the validation of a prospect's structure is approaching a science.
However, validation of the anomaly's cause is still an art that requires rules-of-thumb that relate the seismic amplitude to both the rock and
pore-fluid properties. Topics covered are: 1) rock properties 2) elastic properties (p-wave, s-wave velocities and density) 3) stack and pre-stack
seismic amplitudes 4) recognizing hydrocarbon signatures in different depositional environments 5) predicting seismic responses from wet and
hydrocarbon saturated intervals as recorded on conventional well logs 6) sensitivity of various seismic amplitude attributes to Class 1,2 and 3
AVO anomalies, and 7) numerous case-history examples of Class 1, 2 and 3 AVO environments that illustrate amplitude interpretation rules
and also introduce new interpretation concepts.

ABSTRACT

The Jurassic Louann salt in the East Texas Basin has played a dominant role in influencing the structural and depositional history of the basin, particularly during the Jurassic and Cretaceous periods. Salt tectonics is closely associated with sandstone distribution, depositional facies, and reef growth, and consequently, with petroleum traps in the basin. Salt withdrawal basins, developed during the Early Cretaceous in response to salt movement, dissolution and diapir growth, are characterized by the presence of an expanded section of Lower Cretaceous marine and deltaic sedimentary rocks. Recognition of fault sets associated with the evolution of these salt-withdrawal basins has gone undetected until the recent Coherence Cube processing of a nonexclusive 3-D seismic survey conducted by Schlumberger in the La Rue dome-Fairway Field area, Henderson and Anderson Counties, Texas.

Images from Coherence Cube processing aptly exhibit extraordinary sets of concentric ring faults that comprise the periphery of two salt withdrawal basins. The Fairway oil field (cum. prod 209 MMBO and 790 BCF) is located at the junction of two sets of ring faults. Early Cretaceous age of the ring faults establishes that these faults are a significant structural element in evaluating petroleum migration patterns and traps within the basin.

The recognition of the ring fault system organization, and its association with the Lower Cretaceous age salt withdrawal basins, provides a guide to exploration for a variety of structural traps that can occur among the ring faults. The most common trap geometry would be defined by two- or three-way dip closures between a pair of parallel ring faults. Where complex relative ring fault displacements are present a horst block trap can occur between a pair of ring faults. This latter type of trap has been found productive in the Sand Trap gas field (cum. prod. 37 BCF). A more speculative play type is the expectation that closely-spaced ring faults may host fractured reservoirs within low porosity and permeability limestone and sandstone formations that comprise the greater part of the Lower Cretaceous rocks. The discovery of Early Cretaceous ring faults in the East Texas Basin by Coherence Cube processing brings new perspectives to development and exploration drilling in this mature petroleum province.

Biographical Sketch
Steven J. Maione, senior staff geologist for the Reservoir Technologies Division of Core Laboratories, received degrees in Geological Engineering and Masters in Geology from the Colorado School of Mines. In 1971 he joined Union Oil Company of California (now Unocal Corp.) as an exploration petroleum geologist in Casper, Wyoming.

In 1974 he joined Unocal's Geothermal Division and participated in geothermal exploration projects in North America, Philippines, Indonesia and Japan. In 1992 he transferred to Sugar Land, Texas, and rejoined the Unocal oil and gas exploration division and participated in teams evaluating new venture opportunities, including China.

In 1997, Steve became an Associate of Valenti Engineering Services of Kingwood, Texas, where he carried out 3-D seismic interpretations. He joined Coherence Technology Company (CTC) in Houston in 1998, specializing in integrating Coherence Cube seismic volumes in 3-D seismic interpretations. Following acquisition of CTC by Core Laboratories, his seismic interpretation work for the Advanced Reservoir Geophysics Group now includes 3-D projects that integrate rock properties derived from seismic (LambdaMuRho, or LMRTM analysis).

Steve is a member of the Houston Geological and Geophysical Societies, the Society of Exploration Geophysicists, Sigma Xi, Rocky Mountain Association of Geologists, and a 32-year member of the American Association of Petroleum Geologists.

Saturday, October 18, 2003: 18th Annual GSH Sporting Clays Tournament at the American Shooting Centers, 16500 Westheimer Pkwy. The tournament is an all day event and family participation is encouraged. Non-GSH members are welcome.

The tournament is a 50 bird event, designed to simulate actual field conditions. Shells are provided, however you must bring eye and ear protection. Prizes will be awarded for shooting prowess in various levels of expertise. Cost is $60.00 per shooter.

BBQ lunch and refreshments are provided throughout the day. Door prizes (made possible through corporate and private sponsorship) will be awarded after the conclusion of shooting.

Please ask your company to help sponsor this annual event. It is through the sponsor donations that we are able to have such good door prizes each year. Feel free to call me if you have questions, or pass my name on other interested persons.

For more information, contact: Tom McCarroll at (832) 366-1623 ext. 205 or tmccarroll@cheypet.com. Please use reservation form in GSH newsletter to register.
